Systems

 

 

Integrated electrical and low-voltage systems of all types—inside and outside a building—encompass the range of work that electrical contractors do. The articles in this section highlight different types of work, from security, fire and life safety, to traditional electrical power and distribution, to lighting, cabling and more. 

Intrepid Electronic Systems operates from two locations in California—Oakland and San Jose—with 25–35 employees at each location. Founded in 1997, the company focuses only on low-voltage systems. 
 “I have been doing this kind of work myself since 1976,” said Kurt Brinkman, owner.


The evolution of data center technology is outpacing changes in nearly every kind of commercial building, making the data center installation and service market lucrative. However, it comes with plenty of challenges.

Last month, we looked at how dark fiber is tested to determine its capability of supporting newer, faster transmission networks. Once dark fiber has been tested and its usability confirmed, communications systems can be connected.


Some cabling industry stakeholders predict the imminent death of copper cabling, while others disagree. However, most agree that fiber optical networks are taking a large bite out of the new network market.
